A day after Barry Zito held the Detroit Tigers to one run in 5 2/3 innings, the Giants will hand the ball to Madison Bumgarner.

Bumgarner, 23, had a solid regular season (16-11, 3.37 ERA, 191 strikeouts), but he went 2-4 with a 5.89 ERA in his final seven starts. And he has been roughed up in his two postseason starts (0-2, 11.25 ERA).

Although there is concern that Bumgarner’s workload (200-plus innings in each of the past two seasons) has caused fatigue, the Giants believe his problems are mechanical. So, pitching coach Dave Rightetti has worked with the lefthander in bullpen sessions.

"I feel good about Madison," Bochy told the Giants’ website. "He's had a great year. He's done a great job for us since he's been up here, including postseason. This is a small sample on a couple hiccups he had earlier, and I think he's getting some much-needed rest and some time to work on making a couple adjustments in his delivery. Sometimes you get out of sync and it's better off taking a little bit of time and trying to sort that out, which he's done.”
